CASEMEN T-WIN DOW HARDWARE.

Original No. 1,334,412, dated March 23, 1920, Serial No. 280,857, filed reissue filed April 23. 1920. Se'ri'al No. 376,154.

To all whom it may fr..(mcern:

be it known that I, FRANK W. S'rnvENs, a citizen of the United States, residing at Newton, county of Middlesex, State of Massachusetts, have invented a certain new and useful Improvement in Oase1nent-lVind0w Hardware, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to fittings for casement windows of the type which are hinged vertically to swing outward and also may be moved from. one side to the other of the window frame on tracks or ways. located on the window stool and lintel respectively. 1 am aware that fittings heretofore been made, but such fittlngs have not been satisfactory, chiefly for two reasons. First, because the windows have frequently become detached from or ways and have fallen to the ground 1njuring the window or passers-by, and second it has been impossible to keep such windows air and rain tight when closed. The devices embodying my invention obviate both of these difficulties and are simple and inexpensive to construct.

The invention will be fully understood from the following description when taken in connection with the accompanying drawings, and the novel features thereof will be pointed out and clearly defined in the claims at the close of this specification.

in the drawings, Figure 1 is a View in elewindow to which is applied a set of fittings embodying myinvolition.

Fig. 2 is a section on line 2-2 of Fig. 1.

Fig. '3 is a section on line 3-3 of Fig. 1.

Fig. 4 is a plan View on an enlarged scale of the top hanger.

Fig. 5 is a View the bottom hanger.

Referring to the drawings, at 11 is shown the window frame. At 12 is shown the window stool and at 13 is shown the window lintel. In the drawings, I have shown two casement window "sashes 14 and 1-) ,hinged on an enlarged scale of lintel are secured tracks respectively. These ways are identical and are constructed from suitable metal, as for. instance, brass. Each way has an interior channel as having an opening all aiong its front face. The 0 )ening f is narrower than the total height 0 the chanthe stool and the or ways 17 and 18 Specification of Reissued Letters Patent.

of this type have the grooves way 18.

On the front edge of both Bcissued Nov. 23,1920. March 5, 1919. Application for sash. The sash swings on the lug asthe window opens. The bottom lug 19 has an enlarged end a which fits into the channel a and cannot be withdrawn through the opening 6 but can slide along it. The shape of the lug will be clearly seen in Fig. 5. The

lug is inserted through the open end of the way before the way is put in place and carries the load imposed by the down thrust of the sash. There is also an im-vard thrust which is taken by the lug when the window is open. Another function of the lug 19 'is to form a pivotal support on which the sash may swing in the face of the sash which is adjacent the-way 17, there is a groove which cooperates with the rib d to make I this part of the sash air and rain tight. ()1) the top of the sash there is a plate 26. and to this is pivotally attached the lug 20. This lug also has an enlarged end which is received Within the channel in the The function of this lug is to prevent the upper eud of the sash swlnging outward and also to afford a pivotal support for the sash. No load is carried by the upper way 18 except what is imposed by the tendency of the sash to fall outward. The two ribs (1, d cooperate with grooves f, f in the inner face at the top and bottom of the window sash, and these form wind and water joints at, these points.

provide each side of the frame of the window with a vertical V-shaped rib of metal 28 which cooperates with the *roove 29 in the proximate face of the sash. similar rih- 30 and groove 31 are formed on the edges of the sash which are hinged together when a double sash is employed. This renders the joints at these points completely water andwind tight.

It will be seen that the herein described fixtures are such that. *';.either of the lugs 19 or 20 can possibly be disengaged from its appropriate way. and therefore there is no possibility that the sash can get unfastened and fall. The sash can be readily moved from one part of the Window to another since t rests chiefly on the lug and not on the rib.

" way secured said ways having a channel formed there1n I therein,-. s'ai'c l gs n i g 5 a pfie in the-sash" window is closed.
